F^TM Program Examples

F is a trademark of The Fortran Company.

Examples of code that use the features of the F95 version of F can be found at the F ftp site. In addition to versions of the examples listed below, there are programs that

• use a user-defined function in a specification statement (spec_fn.f95),
• test the SLATEC library (asinh.f95, test_gamma.f95),
• call a Fortran 77 program (f_calls_f77.f95, f77sub.f),
• call a C program (f_calls_c.f95, csub.c),
• access environment variables command-line arguments (args.f95), and
• call system to execute POSIX commands (system.f95).

The examples of F programs provided here illustrate several features of the F programming language (F95 version).

• Alan Miller provides a quad precision module and many other useful routines written in F.
• Computation of the factorial function
• An iterative computation of square roots
• Using nonadvancing I/O, cycle, and exit statements to count the number of characters in a file
• Dynamic and optional dummy arrays
• Modules containing constants
• Rolling Dice
• Towers of Hanoi
• The Sieve of Eratosthanes
• Nonadvancing I/O
• Adaptive Trapezoidal Quadrature; a nice example of recursion in a "real" numerical program!
• A heat transfer program using array sections
• A heat transfer program using pointers to array sections
• A generic procedure to swap values of various data types
• A binary tree sort
• A program to generate magic squares
• A module of programs to compute with very large integers
